Abstract (en)
[origin: US4423653A] Band saw blades embodying this invention are especially adapted for the cutting of hard metal work pieces of large cross-sectional size. The blades are characterized by a straight, planar sawtooth cutting edge and a tiered or stepped back edge, having alternate recessed and outer edge portions. Both the recessed and outer edge portions of the blade's back edge are generally parallel to the cutting edge of the blade and adjacent of these alternate edge portions are connected with inclined or tapered sections. The length of the recessed and outer edge portions are approximately equal; and when combined with the length of an inclined section, is about equal to the spacing of the saw guides of the band saw machine in which the blade is to be used.
